When that day comes [i.e., after His ascension (?)], you will know that I am in [fellowship with] the Father, and that you are in [fellowship with] me, and that I am in you [i.e., through the Holy Spirit].
And God lives in the heart of the person who [continually] obeys His commands, and he lives in [fellowship with] God. And here is [another] way we know that God lives in our hearts: It is by [means of] the Holy Spirit, whom God gave to us. [See Rom. 8:9, 11; James 4:5; I Cor. 6:19].
Look, I am standing at [your] door and knocking; if anyone hears my voice [i.e., the sound of my knocking], and opens the door, I will [surely] come in to him and eat with him and he [will eat] with me.
Jesus answered him, “If a person loves me, he will obey my teaching, and my Father will love him and we will come to him and make our home with him [i.e., in the person of the indwelling Holy Spirit].
No person has gazed upon God [at any time]; [but] if we love one another, God [continually] lives in our hearts, and His love is made complete within us.
And what agreement is there between a temple of God and idols? For we are a temple of the living God, just as God said [Lev. 26:12], “I will live in them and walk among them [i.e., among His people]; and I will be their God and they will be my people.”
You people should continue [to practice] what you heard from the beginning [i.e., to love one another, See verses 7- 11]. If you do, then you also will continue in [fellowship with] the Son, and with the Father.
